Last night Grauman's Chinese Theatre in LA played host to the extremely colourful premiere of Katy Perry's debut concert movie - Part of Me. A 3D film that's sure to break new cinematic frontiers (cough cough), Part of Me offers a fly on the wall insight into Katy's hectic past year, chronicling the rise and fall of her marriage with Russell Brand, among other exciting revelations. Oooh, Juicy.

As per The Daily Mail, the documentary movie kicks off just two months after Perry and Brand were married and follows the star right through her hit California Dreams tour.

Jam packed full of teeny bopping pop princesses, this pink carpet posse would be many a hard core music geek's worst nightmare. Carly Rae Jepson, Rebecca Black and Selena Gomez all under one roof? Yikes.

While this is Katy's first foray into the world of cinema, she certainly did look the part in her Dita Von Teese-esque classic Hollywood get up. The 27 year old Wide Awake singer wowed the crowds in her strapless red velvet number, accentuating her voluptuous curves and itty bitty waist. Still rocking that granny-style purple rinse, Miss Perry matched her outfit with vintage hair,  PERFECTLY applied make up and simple accessories. Bravo Katy, Bravo.

Speaking of grannies, here's Katy's nan with the most stylish of walking sticks I've ever seen. If I ever need one myself, I'll know who to give a call. And here's the starlet's mammy and daddy, Keith and Mary. Don't you just love his hipster glasses? Now we can see why Katy's so cool.

Now usually I'm pro Selena Gomez but this Barbie style mini dress with fluffy bits and sequins isn't doing much for my mojo. Also, I think I preferred her hair darker and shorter. Bit too tweeny with these extensions if you ask me. Meanwhile Carly Rae Jepson blinds us in bright yellow shoes and a satin blue dress and here's Rebecca Black paying homage to the Part of Me star (I'm assuming) with her dip dyed pink hair.

Out of interest, will any of you be interested in seeing this flick?
